The Australian Securities Exchange (ASX) is implementing Amazon Bedrock, AWS’ cloud-based service for building generative and agentic AI applications, to enable AI access to market data from FY27. Speaking at the AWS Financial Services Symposium Sydney, chief information officer Tim Whiteley placed AI on its technology modernisation roadmap, but said AI-related deliveries will occur only after more core ASX systems are modernised. Most modernisation focus is on the second attempt at a Clearing House Electronic Subregister System (CHESS) replacement, stage one of which went live in late April. Additional staged core systems modernisation activity is planned between now and “early 2027”, in partnership with TCS, Accenture and AWS. Whiteley outlined at least three envisioned AI uses: helping customers consume data with AI, noting old market data feeds won't work the same to support AI consumption; making unstructured data from company announcements filed as PDFs available to customers for their AI; and improving internal productivity and access to data. He said additional AI use cases could emerge between now and FY27.
